The development of rural areas is expected to be holistic covering all essential infrastructure. Community information centres (CICs) are agen- cies that should be part of the infrastructures for rural development. Unfortunately, these centres are hardly seen in rural communities in Nigeria, including Afikpo in Ebonyi State. Thus, this study was conceived to explore the perceptions of citizens towards the establishment of CICs in the locality. It adopted survey research method with questionnaire as instrument for data collection, which was self-developed and validated by experts with a pre-texted reliability index of 0.72. A total of 399 copies of the questionnaire were distributed, out of which 267 copies were properly completed, representing 67% and were used for analysis. Findings revealed that the citizens have overall positive perception to- wards establishing the CICs; they are also knowledgeable of the benefits of such centres. Furthermore, there are workable suggestions on ways of establishing, funding and managing CICs in Afikpo. In addition, about 65% of the respondents indicated interest to assist and support the funding and management of the CICs when established. However, the challenges of inadequate funding and support as well as the possible politics of where to site/locate the CICs in Afikpo, are likely impediments to the project. The study concluded that citizens have strong and positive disposition towards establishing CICs in Afikpo. The implications of such CICs for technological innovations were analysed. The study recom- mends, among others, that government should see the establishment of CICs as priority projects that would significantly contribute to the growth and development of rural communities in Nigeria; communities in Afikpo should explore self-help approach to development; and political representatives from Afikpo should take advantage of establishing CICs as constituency projects for the citizens.

본 연구에서는 학생들의 과학 기술관련 사회쟁점(SSI)에 대한 의사결정과정을 탐색하는 방안으로 기술의 본성(NOT)을 제안하였다. SSI 의사결정과정에서 자주 언급되는 논점들은 과학 지식 및 지식의 형성과정에서 추출된 과학의 본성보다는 인간이 필요로 하는 도구를 만들거나 사회에서 벌어지는 다양한 문제를 해결하고자 개발되는 기술과 더욱 밀접하게 연관되기 때문이다. 이에, 서울 소재 대학교에 재학중인 45명의 학생들을 대상으로 GMO(황금쌀)에 대한 시나리오를 제공한 후, 그에 대한 의사결정 내용을 글로 작성하도록 하였다. 글쓰기에서 드러난 학생들의 주요 논점은 네 가지로 요약될 수 있었다. 첫째, 과학기술 인공물이 사회문제를 해결할 수 있을까? 둘째, 해당 사회문제를 해결하기 위한 다른 대안은 없을까? 셋째 과학기술 개발과정 및 관련 제품이 유통되고 사용되는 과정에서 발생할 수 있는 부작용 혹은 문제점은 없을까? 넷째, 과학기술의 불확실성이 존재하는 상황에서 어떤 대응을 해야 할까? 연구자는 이 네 가지 논점을 문헌에서 추출한 기술의 본성(NOT)(문제의 해결안으로서의 기술, 문화적 맥락과 가치의 역할, 기술적 트레이드오프, 시스템으로서의 기술, 기술적 진보)의 관점에서 해석하였다. 그 결과, NOS와 달리 NOT는 학생들의 주요 논점에서 명시적으로 드러났으며, 이를 통해 학생들의 기술에 대한 이해 수준도 가늠해 볼 수도 있었다. 이는 SSI 맥락에서 합리적인 의사결정 능력을 함양하는 방안으로서 NOT의 적용가능성을 시사한다.

Technological, policy and economic factors are both important variables in maximizing the results of a national R&D program and key indicators in evaluating an R&D program's eligibility for financial support. Economic analysis, in particular, is used when selecting R&D programs, setting priorities, and estimating economic effects. This paper examines a series of methodological issues related to the economic analysis of national R&D programs within the framework of the current preliminary feasibility evaluation system, and proposes alternative approaches to each of the issues discussed. The issues include the definition of R&D valuation and establishment of valuation factors; estimation of sales attributable to R&D investment; assessment of the total economic value of R&D as intellectual assets; estimation of R&D benefits and assumption of related to sales; and the application of discount rates based on the weighted average cost of capital. Finally, this study presents directions for future research on analytical procedures and methods of improving the reliability of the results of economic analysis within the national technology planning system.

Technological feasibility of using recently-available femtosecond ultra short pulse lasers for advanced precision length metrology is investigated with emphasis on absolute distance measurements with $10{\mu}m$ ??resolution over extensive ranges. The idea of using femtosecond lasers for the measurement of absolute distances is based on the fact that a short pulse train is a mode-locked combination of discrete monochromatic light components spanning a wide spectral bandwidth. The synthetic wavelength is created from the repetition frequency, $f_r$ of the femtosecond laser and for more precise resolution, higher-order harmonics of the repetition frequency may be selected as the synthetic wavelength by using appropriate electronic filters.

The objective of this paper is to design a Goal Alternatives Disposition System having three main subsystems for setting, evaluating and selecting goal alternatives. For setting of goal alternatives, System Alternatives Tree(SAT) structure will be developed, which has a computation algorithm for setting decision alternatives by the concept of System Priority Number(SPN). For evaluating and selecting of goal alternatives; First, Normative and Exploratory Priority Indices which consider technical performance to the goal, cost and feasibility are developed respectively. Second, Integrated Priority Index is built up to determine the total priority of the Goal Alternatives Disposition(GAD) system. For the design and verification of the GAD system, technological forecasting structure theory, systems engineering methodology will be used.

Objectives This study presents a methodology that enables a quantitative assessment of green chemistry technologies. Methods The study carries out a quantitative evaluation of a particular case of material reutilization by calculating the level of "greenness" i.e., the level of compliance with the principles of green chemistry that was achieved by implementing a green chemistry technology. Results The results indicate that the greenness level was enhanced by 42% compared to the pre-improvement level, thus demonstrating the economic feasibility of green chemistry. Conclusions The assessment technique established in this study will serve as a useful reference for setting the direction of industry-level and government-level technological R&D and for evaluating newly developed technologies, which can greatly contribute toward gaining a competitive advantage in the global market.

It has been asserted that information technology (IT) is being exploited by a number of corporations for strategic advantage. The successful implementation of an organization-wide IT, however, not only depends on its strategic and technological feasibility, but also on the effectiveness of organizational transformation strategies. In this case, the organizational transformation strategy and its success for the adoption of computerized typesetting systems (CTS) by one of the largest Korean newspaper companies, are described With an analysis on the Korean newspaper industry, the case explains the internal and external pressure towards the introduction of the new information technology and its development process. It also provides the architecture and operational mechanism of the CTS. Finally, the case analyzes the impact of the system on the competitive behaviors of the rivals in the industry.

The aging society comes, the number of the old people expended. Technical aids allow elderly and handicapped people to live independently in their private homes as long as they wish. As a contribution to these required technological solutions, a demonstrator platform for a walking assistance robot. robot which has the capability to perform fetch and carry and various other supporting tasks. In this study, we addresses the development of a walking assistance robot system. We execute static analysis, vibration analysis and flexible dynamics to reserve stability at the design. Each motion of the robot uses a linear actuator and gears. Motion can be distinguished into 3 parts depending on the up & down, rotation, and cushion trans. In each motion, we compare the displacement of the case to be rigid with the case to be flexible. As a result, manufactured and feasibility of the walking assistance robot is validated through preliminary experiments.

Aggregate bandwidth required by the internet is expected to be explosively increased. To meet this anticipated need, an ultra high speed internet backbone transport network, capable of supporting up to a Tbps traffic capacity, is required. this thesis examines, through computer simulation and modeling, the technological requirements and assesses the performance analysis and feasibility for implementing ultra-high speed NGI backbone transport network fabric based on WDM technology. The study results are that C/L band EDFA spectral gains for ultra high speed DWDM have been improved from 2.61dB/1.5386dB to 0.03dB/0.096dB by proposed architecture.
